The way Controller for HomeKit lets you scan your home and build an interactive floor plan with all your accessories overlaid on top is the best UI for HomeKit I've ever seen. It's so intuitive that it almost feels like it belongs in Apple's own Home app for the iPhone.

Controller for HomeKit is an alternative way of controlling and setting up your HomeKit accessories, scenes, and automations from your iPhone.
